“…1,10 To note, after aortic valve replacement, LA remodelling is also associated with clinical outcome. 13 In the present study, LA vol max was related to all atrial phasic volumes. However, only LA passive volume (larger) and LA active fraction (reduced) were significantly different as compared with controls.…”

AimsThe present study sought to determine the relationship between left atrial (LA) volume (structural changes) and LA function as assessed by strain rate imaging in patients with aortic stenosis (AS). Methods and resultsThe study consisted of a total of 64 consecutive patients with severe AS (,1 cm 2 ) and 20 healthy control subjects.The phasic LA volumes and function (tissue Doppler-derived strain) were assessed in all patients. As compared with healthy controls, all strain-derived parameters of LA function were reduced in patients with AS. Conversely, only indexed LA passive volume (increased) (7.6 + 3.8 vs. 10.5 + 5.1 ml/m 2 , P ¼ 0.02) and LA active fraction (decreased) (43 + 6.7 vs. 31 + 13.3%, P , 0.001) (volume-based parameters) were significantly different between AS and controls. In AS, LA volume-derived function parameters were poorly correlated with LA strain parameters. In fact, by multivariable analysis, no LA phasic strain parameters emerged as independently associated with LA phasic volume parameters. ConclusionsIn AS, changes in LA function did not parallel changes in LA size. Furthermore, the increase in LA volume does not necessarily reflect the presence of intrinsic LA dysfunction.--

“…The powerful prognostic value of LAD in CHF patients with preserved ejection fraction shown here is consistent with previous studies using left atrial size to predict survival in dilated cardiomyopathy [13], restrictive cardiomyopathy [14], acute myocardial infarction [28], congestive cardiac failure [29] and post-valve surgery [30]. Aortic diastolic pressure was also prognostically significant.…”

“…Left atrial (LA) size has been shown to be a marker of diastolic dysfunction and is related to cardiovascular morbidity in various cardiovascular diseases (CD) [1][2][3][4][5][6]. An alteration in LA size may imply the progression of cardiac disease and LA volume appears as a more robust marker of adverse events than LA diameter or area [7].…”
